Even though Earth Day was a couple days ago, I just decided to share this project today because I wasn't quite done yet. This was really just a one-hour vector art project.
I use a site called Vectr for all my art. They have paying options, but it's really just fine without. There's no download or anything, and they have better vector art tools than the ones on Scratch. I can't code at all, so thanks to @galaxyturtle2 for showing me how to fade this (one of the most simple things to do on Scratch, I know :). You should give him a heart and star.
